I question her whole pattern of thinking. If for some reason killing some older giraffes would strengthen the herd, why would she be celebrating it. She is excited about her kill and is now trying to justify it to cut down on the criticism.

The male might have been older, but he was probably one of the strongest members of the herd. If they want giraffe herds to be strong they should stop killing the predators who kill the weak members. Human hunters kill the strong so they weaken the herd.

I don't understand these hunters and their need to destroy life. Is their something missing in them that they can only fill with death. It is not just that they kill, they seem to need to show off pictures and boast about it.

This is not the same thing as people from an earlier time hunting for food to feed a family. No one like that ever felt the need to post pictures and show off what they shot. They simply did what they needed to in order to survive.
